New Delhi, Sept. 1 (PTI): Afghan security forces have arrested seven persons in connection with the attack on the Indian consulate in Jalalabad yesterday.

One of those arrested had lobbed the grenade that exploded in a drain near the side entrance outside the consulate, said a spokesperson of the external affairs ministry.

“There was no damage or casualties,” said the spokesperson. Official sources added that there was no damage to the consulate in the attack and it was “functioning normally”.

Around 8 pm, an individual travelling on top of the leading mini-truck of a two-truck convoy lobbed the explosive, said the spokesperson. The blast left a hole in the front perimeter wall of the building and broke some windows inside.

The grenade was tossed into the building from one of the cars before they sped away, provincial police chief Gul Karim had said yesterday.

“Those involved have been apprehended by the Afghan security forces,” the spokesperson said. “We await the results of their interrogation.”

The Indian consulate in Jalalabad is headed by consul general R. Tandon.

The sources claimed that there have been persistent intelligence reports about plans by the ISI to derail the security of the Indian consulates in Jalalabad and Kandahar.
